CAD MCP Server

Give your AI assistant the ability to inspect, measure, and compare 3D CAD models. Drop in a STEP file, ask engineering questions, get measured answers. Runs entirely on your machine - no cloud, no CAD license, no setup. It runs locally over stdio via the published package.

People who work with b rep, cad and dfm and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

{
  "mcpServers": {

      "command": "npx",
      "args": [
        "-y",
        "cad-mcp-server"
